Abstract

A sound-effect setting method and an electronic device are provided. The sound-effect setting method comprises decoding an audio data stream; performing sound-effect processing on the decoded audio data stream according to a sound-effect parameter to obtain sound-effect processed audio data; encoding the sound-effect processed audio data to obtain encoded data and outputting the encoded data and the sound-effect parameter.
